Patent FR-2230327-A1 (FR)
Title: Dental channel measuring probe - has alternate zones visible and invisible on and tip visible on X-ray image
IPC: A61C19/04
Filed: 1974-05-22
Abstract: The probe for introduction into the channel to be measured comprises alternate zones, visible and invisible on the X-ray image. These zones can be of the same length, a visible one being situated at the tip. The material of the probe can be invisible on the image, the visible zones being formed by metal coatings deposited by vapourisation or galvanic action. The bar of the probe can be plastic. The use of a tip visible on the X-ray image ensures that the probe has been inserted as far as the end of the tooth root.

Title: Splash absorber for top-poured steel ingot moulds - made of corrugated paper coated with aluminium
IPC: B22D7/12
Filed: 1974-07-19
Abstract: In a shock absorber for the top during of ingots, at least some of the surfaces of the combustible material forming the vertical walls of the absorber are coated with a layer based on aluminium. The layer of aluminium pref. consists of an aluminium foil flued onto the flat surface of corrugated paper or cardboard, or glued onto one or two surfaces of cardboard forming a honeycomb structure; alternatively, the Al coating may consist of an Al-base paint. The thickness of the aluminium layer is pref. calculated as the wt. necessary for deoxidation of a steel ingot. This device prevents splashes of molten steel from being thrown onto the mould walls; provides uniform deoxidn. of the steel and the Al retards the destruction of the cardboard so the absorber is more effective.

Title: Malignant neoplasm or benign tumour diagnostic apparatus - uwing using thermographic infra red spectrum diagram investigation of tissue
Inventor: COSTACHEL OCTAV
IPC: A61B5/00
Filed: 1974-10-07
Abstract: The spectrum diagram of the whole infra-red spectrum is analyzed and the type of disease identified by comparing the shape of the diagram, band width of the occupied bands and their degree of displacement with the corresponding values from a healthy tissue spectrum diagram. Preferably, the infra-red rays of a hot spot are split by a monochromatic band filter or the prism of a monochromatic illuminator and the output signal transformed into an electrical signal which is then electronically amplified and recorded. The variation curve of the monochromatic radiation intensity is shown as a function of its wave length, by means of a coupling linking the system of successive selection of the monochromatic rays and the recording sheet drive system.

Title: Electronic ignition signal generator - signals are amplified to advance ignition corresponding to engine speed
IPC: F02P7/067
Filed: 1975-03-26
Abstract: The generator consits of a laminated horse shoe shaped magnet core with a primary and a secondary winding. The distributor shaft turns a cam arranged between the core pole shoes to interrupt the magnetic field in synchorisation with the ignition timing. The primary coil is fed from the vehicle battery via a diode and a filter capacitor. An a.c. of low amplitude is induced into the secondary winding when the cam lobes cut the magnetic field, this current is fed to the base of a first transistor and reformed into positive and negative impulses. The negative signals go to a capacitor and the output connection and part of the positive signals are fed to the second transistor to act as an amplifier. At low engine speed the negative signals have a lower frequency than the positive signals which are transmitted via the resistance to the second transistor which is saturated correspondingly to engine speed revolutions to effect the advance timing accordingly.

Title: Signal correction for non-linear motion - compensating ccts. correct non-linear velocity of photodiode sensing head in file reading
IPC: G06V10/10
Filed: 1975-04-16
Abstract: A signal correcting processor is provided to provide compensation for the non-linearity of the velocity of a carriage containing sensing devices extracting coded information from a file storage unit. The time base for reading is given by a coding unit sensing an optically patterned band that is fixed relative to the reading head carriage. Data is sensed by a strip of photodiodes, the output of which are focussed with a lens system. Lamps are attached to either side of the carriage and are the outputs focussed by condenser lenses onto the specific line of information being processed. If the motion of the carriage is examined over a period the velocity is non-linear with a maximum occurring in mid-period. Analogue circuitry provides compensation for the effects of the non-linearity.

Title: Silencing of multi-engined jet aircraft - has sound waves from two engines arranged to be exactly out of phase with each other
IPC: B64D33/00
Filed: 1976-10-14
Abstract: A method of silencing the jet engines of a multi-engined aircraft consists in so arranging the running of each pair of engines that the sound waves from one engine are exactly out-of-phase with the sound waves from the other engine. If the amplitudes of the sound waves from each engine are equal than the two sets of sound waves will cancel each other completely. Even if the amplitudes are different, the amplitude of the louder sound wave will be reduced by the amplitude of the other sound wave.
